Turn Do Not Disturb On or Off
When Do Not Disturb is active on your Xiaomi phone, calls get an instant busy signal and every notification stays silent, even for messages you actually want to hear. Many people leave it on by accident after enabling it for a meeting or at night, since MIUI does not always show a clear reminder that it is still running. Checking the current status and switching it off takes just a few taps in Sound & vibration settings.
Assign Alarm Functions to Volume Buttons
If your alarm keeps ringing because pressing a volume button does nothing, MIUI lets you change that behavior in the alarm settings. By default the phone treats both volume keys the same way, so you cannot assign a separate action to volume up and volume down. This single setting decides whether a button press snoozes, dismisses or ignores the alarm every single time.
Vibration in Silent Mode: Turn On or Off
When you switch a Xiaomi phone to Silent, it still buzzes for every incoming call or message by default. If you want the device completely quiet without any buzzing on the table, you need a separate toggle beyond the ringer switch itself.
Snooze App Notifications
When a chat app or delivery tracker keeps buzzing during a meeting, muting it completely isn't always what you want. MIUI lets you pause a single notification for a set time instead of turning it off for good. This keeps the alert coming back later without touching the app's notification settings.
Allow or Deny Do Not Disturb Access for Apps
When an app suddenly enables Do Not Disturb on its own, or a call app keeps muting notifications you actually want to see, a hidden system permission is usually behind it. On Xiaomi phones, individual apps can request permission to switch Do Not Disturb on or off, and that access is not always obvious from the app itself. Checking which apps hold this permission helps you regain control over your notifications.
Turn Screenshot Sound On or Off
Every time you capture a screenshot on a Xiaomi phone, a short chime plays to confirm the capture went through. If that sound feels too loud in meetings or you simply want an audible confirmation back, the setting sits separately from your general ringtone volume and needs its own toggle.
Turn Screen Locking Sounds On or Off
Every time your Xiaomi phone locks or unlocks, a short click plays, and it keeps repeating as you use the device throughout the day. That sound comes from the Screen locking sounds option buried in the sound settings, not from notifications or Focus mode. It can be muted or restored in a few taps once you know where it hides.
Turn On/Off Increasing Ringtone Volume
If every incoming call blasts full ringtone volume right away, or the ringtone feels too quiet at first and only gets loud after several rings, the Increasing ringtone volume option is the setting behind that behavior. It decides whether calls start soft and grow to your set volume level or play at full strength from the first ring. This setting sits separately from the general ringtone volume slider and often gets overlooked when troubleshooting calls that feel too jarring or too quiet.
Set Notification Sounds for Each App Individually
When every app on your Xiaomi phone plays the same notification tone, it gets hard to tell a messaging alert from a random app update without looking at the screen. MIUI lets you assign or mute sound per app, but the option sits inside a settings area many users never open. Here is where that control actually lives and how to change it for one app at a time.
Change Alarm Tone
If your Xiaomi alarm keeps ringing with the same generic tone or the Nature alarm sound never changes, the ringtone categories in the Clock app are likely the reason. Some categories, like Nature alarm, only rotate through different sounds when the phone has an active internet connection. Without that connection, the alarm falls back to a stored default tone instead of downloading a new one.
Turn Delete Sound On or Off
Every time you delete a message or a file on your Xiaomi phone, a short click sound plays automatically. That extra sound gets annoying fast if you delete things often or want your phone quieter in general. The setting sits with the other system sounds, not inside the messaging app itself.
Show or Hide Notification Icons in the Status Bar
When your status bar stays empty even though an app has new messages, the notification icon display in MIUI might be switched off. This setting decides whether small app icons show up next to the clock so you can spot new activity without unlocking your phone. If it is disabled, you will only notice new notifications once you pull down the shade.
Turn Lock Screen Notifications On or Off
Hiding lock screen notifications on your Xiaomi phone keeps message content away from prying eyes, but it also means pop-up alerts stop appearing when the screen is locked. Instead you only see small icons in the status bar, so you have to unlock the phone to check what actually happened. This trade-off between privacy and quick alerts confuses a lot of users switching the setting for the first time.
Turn Battery Drain Notifications On or Off
If your Xiaomi phone keeps popping up alerts about fast battery drain, or you never get one and expect to, this setting is the reason. Battery drain notifications warn you when an app or background process burns through power faster than normal. Left enabled, unrelated background tasks can trigger these alerts more often than you would like.
Quiet Ringer When Lifted
If your phone still rings at full volume even after you pick it up during an incoming call, the Quiet ringer when lifted feature might be switched off. This motion-based setting is meant to automatically lower the ringtone as soon as you lift the device, but it only works when enabled in the calling settings. Without it active, you have to manually silence every call yourself.
Turn Focus Mode On or Off
If notifications from social or gaming apps keep interrupting your home office setup on a Xiaomi phone, Focus mode is the built-in tool meant to block that noise for selected apps. Many users only discover the toggle by accident, and the automatic scheduling option often stays unused, leaving the phone unrestricted outside of manual activation.
Adjust Ringtone Volume for Calls and Notifications
If calls ring too loud while notifications stay silent, the culprit is usually the separate volume sliders inside Sound & vibration. Xiaomi phones control ringtone, reminder and notification volume independently, so lowering one slider does not affect the others. This mismatch often causes missed calls or alerts that trigger at the wrong volume.
Allow Repeated Calls in Do Not Disturb
When Do Not Disturb is active on your Xiaomi phone, every incoming call gets silenced, even urgent ones. MIUI has a separate setting that lets a second call from the same number within a short window ring through instead of staying muted.
Schedule Do Not Disturb Automatically
If Do Not Disturb only works when you remember to switch it on, notifications still slip through during meetings or overnight. MIUI can run silent or Do Not Disturb mode on its own recurring schedule, but the settings for start time, repetition and mode type are easy to miss.
Focus & Shoot: Turn On or Off
If tapping the screen on your Xiaomi camera fires the shutter right away instead of just setting focus, Focus & shoot is switched on. Some people rely on this two-tap workflow to keep the phone steady, while others get accidental photos while they are still framing the shot.
Turn Camera Shutter Sound On or Off
Every photo on your Xiaomi phone triggers a shutter click, even in a quiet room or during a video call screenshot. The sound comes from the camera app itself and has nothing to do with your ringtone or notification volume, so muting the phone alone will not silence it.
Turn Call Vibration On or Off
If your Xiaomi phone buzzes loudly on a hard surface every time someone calls, or you can barely feel it while it sits in your pocket, the call vibration setting is likely working against you. This option controls only the vibration for incoming calls, independent from message or app notification vibration. Getting it wrong means either annoying buzzing on a desk or missed calls when the phone is muted and out of sight.
Set Ringtone for Incoming Calls
When every incoming call on your Xiaomi phone uses the same generic tone, or a video calling app ignores your chosen sound completely, the default ringtone setting is usually the cause. Dual-SIM users often run into a second issue: one SIM plays the wrong tone because each line can carry its own ringtone. Both problems trace back to the same sound settings that MIUI applies system-wide.
Change Ringtone for Event Reminders
If every calendar reminder, note alert, and task notification on your Xiaomi phone plays the same generic tone, it's easy to miss what actually matters. Event reminders use a separate sound slot from calls and messages, so changing your default notification tone alone does nothing. MIUI lets you assign a dedicated tone just for these reminders, from either Xiaomi's included tones or your own sound files.
